Not really. It's not that they're exaggerated, they're just complex situations that are more in depth, and you need to think about it. I do agree that in some ways they are exaggerated(soundtracks and animation style can make things seem a lot more emotional and stuff). Saying they have a "specific theme to amuse the target audience." is pretty much untrue. By "theme" I don't mean topic, I mean like a very broad concept in general, IE truth discovery love hapiness etc. Kinda hard to explain, and you need to decide what is meant for yourself-it isn't "specific" at all.
